| 1 | Antioxidant and cytotoxic activity of Acanthus ilicifolius flower显示文摘Objective:To investigate the antioxidant and cytotoxic activity of the flower of Acanthus ilicifolius(A.ilicifolius).Methods:Antioxidant activity was determined as antiradical efficiency with diphenyl picrylhydrazil(DPPH)method and cytotoxic assay was undertaken using brine shrimp lethal toxicity test.Results:A.ilicifolius flower contained terpenoid,phenolic compounds,and alkaloid.The methanol extract of A.ilicifolius flower showed the highest antiradical efficiency(AE=1.41×10^(-3))against DPPH radicals and the highest cytotoxicity(LC_(50)=22μg/mL)against brine shrimp nauplii.Conclusions:It is suggested that active compounds of A.ilicifolius flower solved in methanol play a role to inhibit free radical activity and kill Artemia salina nauplii.The substances can be considered as potential antioxidant and cytotoxic agents as well as imminent candidate for cancer therapy. | Muhamad Firdaus Asep Awaludin Prihanto Rahmi Nurdiani | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，1： | 3 |
| 2 | Cold Plasma:A Potential Alternative for Rice Grain Postharvest Treatment Management in Malaysia显示文摘Use of pesticides,herbicides and fertilizers is among the techniques to control insect pests and fungal pathogens.However,the technique is the major contributor to severe environmental implications in terms of air,water and soil pollution.Besides,variable inconsistency becomes an important issue in the implementation of inclined bed dryers,leading to significant rice grain loss.Cold plasma technology has been widely proposed as a potential alternative for rice grain postharvest treatment management due to the presence of generated ionised gas that eventually produces reactive oxygen species or reactive nitrogen species.These species are used to decontaminate foodborne pathogens,mycotoxins and bacterial diseases.This review explores the current literature regarding cold plasma treatment technology,focusing on its efficiency as the microbial decontamination medium and insect pest mortality medium,and on the enhancement functional,nutritional and cooking properties,especially in rice grains.Previous studies have successfully demonstrated the ability of cold plasma treatment to significantly reduce the microbial count of foodborne pathogens,detoxify mycotoxins,and control seedborne rice seedling bacterial diseases.Previous studies have also proved that the implementation of cold plasma technology in postharvest management should be seriously considered for improving rice grain quantity and quality in Malaysia. | Mohd Fadthul Ikmal MISNAL Norizah REDZUAN Muhamad Nor Firdaus ZAINAL Norhayati AHMAD Raja Kamarulzaman RAJA IBRAHIM Linda AGUN | 2022 | Rice science2022，29，1： | 2 |
